Check out our webinars planned for summer 2024:
June 20, 2024 - Flea Control & Diseases: Starting from Scratch
Fleas are small but mighty insects that are important medical and veterinary pests. They can vector pathogens and parasites, and their bites cause discomfort and irritation. In this webinar you'll learn how to keep yourself and pets safe from fleas and flea-borne diseases.
July 18, 2024 - Common Wood Decay Fungi in Landscape Trees of California
Trees are a valuable part of our landscapes. However, older trees can harbor wood decay fungi, which can be associated with an increased risk of tree failure or branch breakage. In this webinar, urban forestry expert Igor Lacan will discuss some wood decay fungi that are commonly seen on trees in urban landscapes in California, the effect(s) of fungi on the tree, and related considerations in tree management.
August 15, 2024 - Back to School Pests
With students heading back to school, now is a good time to talk about pests in schools and childcare centers. In this webinar, Karey Windbiel-Rojas will talk about head lice, bed bugs, rats, cockroaches, and more. We will also cover the use of disinfectant wipes and pesticide safety.
September 19, 2024 - Improving Professional Ant Control Services
In California, the Argentine ant is among the most common nuisance ant species treated by pest management professionals and the general public. In this webinar, you will learn how the university researchers and pest management companies are working together to improve pest ant management in urban residential settings.
Webinar topics for October and November will be announced mid-summer.

Growers Invited to Avocado Lace Bug Presentation
On May 14 at 12:30 p.m., Paloma Dadlani — a graduate student under Dr. Mark Hoddle who has been spearheading avocado lace bug research funded by the California Avocado Commission — will deliver her master's thesis defense seminar. Interested California avocado growers can view the thesis defense online or attend in person at the UC Riverside Entomology Building located at 165 Citrus Drive, Riverside, CA.
The thesis covers the following topics:
- Effects of temperature on developmental and reproductive biology, and degree-day models. This work helps predict development times in the field and will inform growers on possible levels of control from hot weather events.
- Two years of population phenology data from four commercial Hass avocado orchards in San Diego County, and surveys for ALB on non-Hass avocados like GEM, Lamb Hass, Bacon, and Fuerte. Natural enemy surveys are included, and sticky card captures to monitor adult dispersal by flight.
- Updated molecular analyses on ALB populations in San Diego county (the original 2004 population in Chula Vista and National City are still there), including comparisons to the "aggressive" populations in northern San Diego County, Riverside, Los Angeles, and Santa Barbara Counties and the extremely damaging populations in Hawaii.

Look closely at a patch of California golden poppies and you may see a sweat bee (genus Halictus) collecting gold pollen. The pollen basket is on the hind legs but you'll see "gold" also dusting the head and abdomen.
Native bee, commonly known as "halictid bee." Native plant. In fact, the California golden poppy, Eschscholzia californica, is the state flower.
And the rumor that it's "protected" and you'll get arrested if you pick a poppy along a roadside is inaccurate.
The California Department of Fish and Wildlife sets the record straight on its website: "It is often believed that there are laws prohibiting the cutting or damaging of the California poppy because it is the state flower. While there is no law protecting the California poppy specifically, California Penal Code Section 384a(opens in new tab) requires written landowner permission to remove and sell plant material from land that a person does not own, and removing or damaging plants from property that a person does not own without permission may constitute trespass and/or petty theft. However, these laws do not prevent the collection of California poppies on private land by the landowner. California poppies are a beautiful and easy-to-grow addition to your garden, and although you may choose to pick them from your property, they last much longer in the ground!"
Want to learn more about native bees? California has some 1600 species of wild or non-managed bees. Be sure to read California Bees & Blooms: A Guide for Gardeners and Naturalists. It's the work of University of California authors, all with UC Berkeley connections: Gordon Frankie, now professor emeritus, UC Berkeley; Robbin Thorp (1933-2019), UC Davis distinguished emeritus professor who received his doctorate in entomology from UC Berkeley; photographer Rollin Coville, who holds a doctorate in entomology from UC Berkeley, and Barbara Ertter, curator at the UC Berkeley-based University Herbarium and Jepson Herbarium.
The Bohart Museum of Entomology is hosting an open house on bees, both wild and managed, from 1 to 4 p.m., Sunday, May 19 in Room 1124, Academic Surge Building, 455 Crocker Lane. It's free and family free.
